Voyager 1 passed into interstellar space way out past our Solar System some time back, but didn't have certain instruments on board to detect the boundary between our Solar System and true interstellar space. But Voyager 2 does. It has just detected the fall off in the Solar wind (plasma particles from our Sun) and the corresponding rise in interstellar cosmic rays. Watch the video and while watching think about the facts described ... namely that using computer chips hundreds of thousands of times less powerful and with way less memory onboard than todays smartphone, so many discoveries were made by the Voyager spacecraft. And think about the amazing foresight and planning done by the older generation who were then 40+ years younger (!) who thought way ahead to design, build and put instruments onboard to discover and detect stuff 40+ years later ... makes you proud to be part of the Human species ... NASA Voyager 2 enters interstellar space

Ironic, I just watched a documentary about Voyager on Netflix today. Not sure about right now but when the vid was made they said they are still getting a signal from them, 1 trillionth of a watt! Amazing.

And it's not 1 trillionth of a watt ... it's only one-tenth of a billion-trillionth of a watt. Crazy!

. . . and stronger signals from other sources in the Universe are mingled in with Voyagers signals so not only is Voyagers signal weak but it has to be seperated from all the other noise.
